Building OCCT from sources

Before building OCCT, make sure to have all the required third-party libraries installed. The list of required libraries depends on what OCCT modules will be used, and your preferences. The typical minimum is Freetype (necessary for Visualization) and Tcl/Tk (for DRAW Test Harness). See "Third-party libraries" section in Overview for a full list.

On Windows, the easiest way to install third-party libraries is to download archive with pre-built binaries from https://www.opencascade.com/content/3rd-party-components. On Linux and OS X, it is recommended to use the version installed in the system natively.

You can also build third-party libraries from their sources:

• Building 3rd-party libraries on Windows
• Building 3rd-party libraries on Linux
• Building 3rd-party libraries on MacOS X

Build OCCT using your preferred build tool.

• Building with CMake (cross-platform)
• Building with CMake for Android (cross-platform)
• Building on Windows with MS Visual Studio projects
• Building on Mac OS X with Code::Blocks projects
• Building on Mac OS X with Xcode projects
